We've been working hard to answer as many of them as possible. Here's what we have so far, but keep checking back as we gather more information for you.

1. Why now?

Detroit's emergency manager Kevyn Orr said he tried to strike a conciliatory tone with the city's creditors, and that he was hoping for a "consensual process" to resolve disputes out of court -- "...but that didn't happen."

Unfortunately, it became clear that those negotiations wouldn’t be successful for a number of reasons. There was no guarantee all the parties would agree. There was strong disagreement about the restructuring plan.

It became clear that the fight over what little money Detroit has to pay its creditors was going to court, so a dramatic race to the courthouse ensued.

As rumors swirled mid-afternoon about an imminent bankruptcy filing, attorneys representing the city’s pension boards filed a motion for a restraining order at 3:37 p.m. — and raced to the Ingham County courthouse in downtown Lansing for an emergency hearing.

By 4:06 p.m., their efforts were moot. The City of Detroit had already filed the largest municipal bankruptcy in U.S. history — five minutes before Ingham County Circuit Judge Rosemarie Aquilina was set to convene a hearing.

2. What's next?

It’s important to remember that Detroit has only “filed” for bankruptcy. They have not entered into bankruptcy just yet.

Orr believes the city, with its massive amount of debt, will meet all the Chapter 9 requirements. But that’s up to a federal bankruptcy judge.

Unions and creditors will likely argue that the city has not negotiated with them “in good faith.” If they can prove that, it's possible that the bankruptcy request could be denied.

You’ll see a lot of posts explaining “What is Chapter 9 bankruptcy?” -- but to really understand it, you should just go straight to the source. The U.S. Courts website does an excellent job breaking it down for you.

Much has been written about the next steps for Detroit, but Detroit Free Press business reporter Nathan Bomey probably has the most comprehensive look at it with his “12 things to expect” post.

3. What happens to public services?

At the press conference that Orr and Gov. Snyder held Friday morning, they stressed that it's “business as usual" for Detroit.

“Going forward... we will pay our bills,” Orr said.

He said priority will be given to those expenses relating to the health, welfare, and safety of Detroiters.

Chapter 9 bankruptcy is designed so a city can continue to function as it moves through the process. But in the future, services could be cut - something that's hard to imagine in a city already struggling to meet basic needs.

But these cities are not Detroit, so there's no telling just how city services will be reorganized. Gov. Snyder says he sees Detroiters "as his customers":

There will be no change in services. In fact, over time, as the process of reinvestment begins, we expect to provide an improved service, which Detroit’s residents deserve.

4. What's happening to city government?

Under the state's "Local Financial Stability and Choice Act" (Public Act 436), Kevyn Orr will continue to keep his power until either Detroit's finances are set straight, or his term as emergency manager ends.

Emergency managers are appointed for an 18 month term. When the term expires, city government leaders vote whether to retain an emergency manager, or end that person's term.

Orr will continue to oversee major decisions, as he has since he was appointed in March. He is expected to run Detroit during the legal process.

Mayor Dave Bing and the Detroit City Council will still hold office, get paid, and make decisions about day-to-day operations. However, Orr can overrule their decisions and strip their powers if he deems it necessary.

The bankruptcy judge will have almost no power to interfere with how Orr runs day-to-day operations in Detroit.
